Hello Forum, I am trying to set the plot background of a series of plots to be white and for y-axis values above 60 grey. Is there a way to do this? I am trying to highlight values above a certain criteria. Other suggestions are welcome. Thanks.
Maybe use the rectangle() or patch() function to lay down a gray rectangle in the appropriate place in the plot. Be sure to set "hold on" after that and before you plot your actual data.
clf plot(rand(10,1),'-o') yUp = 0.7; x=get(gca,'XLim'); y=get(gca,'YLim'); patch('XData',[x fliplr(x)],'YData',[yUp yUp y(2) y(2)],'FaceColor','r','FaceAlpha',0.3)
